If I were you guys
and found these conditions in Alaska ? I would not recommend replacing as
is. What you guys need is nice volcanic eruption on Mount Shasta or something and 3 or 4 inches of ash to
help speed up gravity.
I have seen old
building roofs that appear to be defying gravity. I have also seen a few roofs
and floors partially collapse or be in the process there of. I
think there is some law in physics that everything in the end will come to
it?s most stable state.

When I first saw
something like this, I had to call Dennis Wish to ask him if this was for
real. It was. All roofs all over a huge apartment complex, may be,
20 years old. Some of the 2x4 rafters had cracked, most sagged
under the weight of the concrete tile roof.
I came up with the
repair details and specs, they paid me OK. However, they indicated that
they were not going to do anything beyond the replacement of the broken
What could I do?
Seriously (as they said), it had been there for 20 years, "nobody got hurt",
and (as I know) there is no snow below 2,000 feet in Southern California...

Another tidbit on
Hips. After Northridge Earthquake I investigated several apartments and
To my amazement On
stick framed roofs I encountered several long span hips and valleys (+25')
where the framer spliced 2x8 or 2x10 at midspan. An engineers dream of
course. The splices were about 2-3 ft. long with a taper cut from
top to bottom of member. 3-4 nails holding it together. These were clean
cuts that went like a puzzle, some I had to look 3 times to make sure of
what I was seeing.
As Nels stated
earlier how do you justify this ?? Some had been there for over 40
Yes, there was
deflection but most people are unaware or cannot even see
